GPRS(General Packet Radio Service)是通用分組無線業(yè)務(wù)的簡稱。GPRS是GSM Phase2.1規(guī)范實現(xiàn)的內(nèi)容之一，能提供比現(xiàn)有GSM網(wǎng)9.6kbit/s更高的數(shù)據(jù)率。GPRS采用與GSM 相同的頻段、頻帶寬度、突發(fā)結(jié)構(gòu)、無線調(diào)制標(biāo)準(zhǔn)、跳頻規(guī)則以及相同的TDMA幀結(jié)構(gòu)。因此，在GSM系統(tǒng)的基礎(chǔ)上構(gòu)建GPRS系統(tǒng)時，GSM系統(tǒng)中的絕大部分部件都不需要作硬件改動，只需作軟件升級。

JILRuntime A General purpose, register based virtual machine (VM) that supports object-oriented features, reference counting (auto destruction of data as soon as it is no longer used, no garbage collection), exceptions (handled in C/C++ or virtual machine code) and other debugging features. Objects and functions can be written in virtual machine code, as well as in C or C++, or any other language that can interface to C object code. The VM is written for maximum performance and thus is probably not suitable for embedded systems where a small memory footprint is required. Possible uses of the VM are in game development, scientific research, or to provide a stand-alone, General purpose programming environment.

zlib 1.2.2 is a General purpose data compression library. All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format) and rfc1952.txt (gzip format). These documents are also available in other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html

CC386 is a General-purpose 32-bit C compiler. It is not an optimizing compiler but given that the code generation is fairly good. There are two versions one is for MSDOS/DPMI and one is for Win32. The Win32 version has a full-blown IDE capable of editing, building, and debugging windows programs included with it. However at this time debugging support for MSDOS is rudimentary at best and there is no IDE for DOS. the newest version, support windows.

ABAQUS is a General purpose finite element analysis program which is widely used to analyses mechanical, structure and civil engineering problems. Abaqus has some special feature for analysing fracture mechanics problems, and therefore it is a main tools for the FE-analysis in the Fracture Group at the Mechanical Engineering at Glasgow Universtity. The software which can transfer data from Abaqus into a Matlab readable environment has been developed as a part of a research program in Constraint Estimation in Fracture Mechanics. This research program was funded by a grant from the Defence Research Agency through Prof. J. Sumpter.
